NICK-BURNER.

Application filed January 17', 1914.

To aid whom it may concern Be it known that I, \Vannnx h'loAnTrrUn, J12,a citizen of the :United States, residing atChicago, in the county ofCook and State of Illinois, have invented a new and useful Improvementin l i iclcliurners, of which the following a specification.

This invention relates more particularly to wick burners for tubularlanterns and is particularly desirable for that class of lanterns inwhich the burner cone is secured to the globe supporting plate and ismoved with the same to and from the wick tube. A. lantern of thatgeneral character is shown,

r for instance, in my Patent No. 1,070,152,

dated August 12, 1913.

Ihe object of this invention istosimplify the construction of the burnerto facilitate the assembling of the partsand to render the burner strongand durable.

In the accompanying drawings: Figure 1 is a perspective view of thecomplete burner. Fig. 2 is a sectional elevation of the same in theplane of the wick raiser shaft, on an enlarged scale. Fig. 3 is a topplan view of the burner. Fig. fl: is a top plan view of the lower partof the burner with the wick raiser shaft, the wick tube being shown insection. Fig. 5 is a sectional elevation of the upper part of the burneron line 55, Fig. 2. Fig. 6 is a sectional elevation of the lower part ofthe burner, on the same line. Fig. 7 is an elevation of a modifiedconstruction of the burner. tional elevation of the same, on an enlargedscale. Fig. 9 is a sectional. elevation of the upper part of the burneron line 99, Fig. 8, and Fig. 10 is a similar view of the lower part ofthe burner on the same line. Fig. 11 is a perspective View of the lowerpart of the burner.

Referring to Figs. 16, the burner there represented comprises four mainparts, a lower body part A, an upper body part B, a wick tube 0 whichconnects the upper and lower parts, and a wick raiser o-r ratchet shaftD to which the ratchet wheels 15 are secured.

The lower body part A comprises a circular shank 16 which is designed tobe seated in the burner socket of the oil pot in the usual way and whichhas in its flat bottom a slot for the lower end of the wick tube. Thelower part A comprises further a horizontal portion 17 which extendsoutwardly from this shank and is provided with large air Specificationof Letters Patent.

passages 18, and has an upstanding marginal flange 19. The latter isprovided on opposite sides with notches 20 for the wick raiser shaft 1).

The upper body part B of the burner coinprises an upwardly taperingportion 21 having large air passages 22 and terminating 111 asubstantially horizontal top plate which. is provided with a slot forthe upper end of the wick tube and with line perforations outside ofsaid slot. This upper part of the burner comprises further a horizontalportion 24: which extends outwardly from the lower end of the portion 21and is provided with a downwardly extending marginal flange 25 havingnotches 26 for the wick raiser shaft, which notches coincide with thenotches 20 in the flange of the lower part. The horizontal portion 24:is provided with large air passages 27 similar to those formed in thelower horizontal portion 17, so that the air can pass freely in anupward direction through the laterally projecting marginal portion ofthe burner when the latter is arranged in the air chamber of thelantern.

The vertical flanges 19 and 25 of the two parts of the burner overlap ortelescope one into the other and the wick raiser shaft is arranged inthe coinciding notches of these flanges. In assembling the parts theshaft with the ratchet wheels secured thereto is laid in the notches ofthe lower part and the upper part is then applied to the lower part andsecured thereto in any suitable manner, for instance, as shown in Fig.2, by means of the wick tube which is clenched at its upper and lowerends over the upper and lower parts of the burner body, respectively,and secures the two parts together with the wick raiser shaft confinedbetween the meeting or lapping edges of the same. or the outer marginalflange of the burner can be bent or clenched over the inserted part. asalso shown in Fig. 2.

This construction of the burner permits the ratchet wheels to bepermanently secured to the shaft before the latter is placed in theburner body and avoids the difficulty often experienced with wheelsworking loose in burners in which the shaft and the wheels areseparately applied and the shaft is introduced through openings in thewall of the burner and thrust through the central openings in theratchet wheels. The man ginal flange of one body part of the burnerrests against the shoulder formed by the other part and is held againstthis shoulder by the Wick tube which ties the two parts together,thereby forming a strong and rigid structure 1n a very simple manner.

The flat top surface of the body portion of the burner, which isarranged on a level with the upper end of the wick tube, takes the placeof the usual wings, flies or tips located at the upper end of the. wicktube.

In the, modified construction of the burner represented in Figs. 711,the vmarginal flange of the lower. part A of the burner is provided withan internal annular bead 31 which forms a shoulder against which theannular, flange 82 of the upper part B rests. This flange is so narrowthat it stands above the wick raiser shaft and air passages, an upwardlyextending portion also provided with air passages and witha flat top, adownwardly extending shank, a

wick tube secured with its upper end in said flat top and with its lowerend in the bottom of said shank, and a wick raiser shaft journaled insaid marginal portion.

2. A wick burner comprising a body composed of a lower and an upper partprovided with lapping marginal flanges, the lower body part comprising ashank adapted to be seated in a burner socket, a perforated horizontalportion extending outwardly from said shank and an upstanding'marginalflange, the upper body part comprising a horizontal perforated portion,a downwardly extending marginal flange on the same and an upwardlyextending central portion having a flat top, and a wick tube arrangedwith its upper end in the upper end of said top portion and with itslower end in the lower end of said shank.
